life cycle assessment of waste paper management the importance of Technology Data and system boundaries in assessing recycling and incineration
Resources Conservation and Recycling, 2008Co-Authors: Hanna Kristina Merrild, Anders Damgaard, Thomas Hojlund ChristensenAbstract:The significance of technical Data, as well as the significance of system boundary choices, when modelling the environmental impact from recycling and incineration of waste paper has been studied by a life cycle assessment focusing on global warming potentials. The consequence of choosing a specific set of Data for the reprocessing Technology, the virgin paper manufacturing Technology and the incineration Technology, as well as the importance of the recycling rate was studied. Furthermore, the system was expanded to include forestry and to include fossil fuel energy substitution from saved biomass, in order to study the importance of the system boundary choices. For recycling, the choice of virgin paper manufacturing Data is most important, but the results show that also the impacts from the reprocessing technologies fluctuate greatly. For the overall results the choice of the Technology Data is of importance when comparing recycling including virgin paper substitution with incineration including energy substitution. Combining an environmentally high or low performing recycling Technology with an environmentally high or low performing incineration Technology can give quite different results. The modelling showed that recycling of paper, from a life cycle point of view, is environmentally equal or better than incineration with energy recovery only when the recycling Technology is at a high environmental performance level. However, the modelling also showed that expanding the system to include substitution of fossil fuel energy by production of energy from the saved biomass associated with recycling will give a completely different result. In this case recycling is always more beneficial than incineration, thus increased recycling is desirable. Expanding the system to include forestry was shown to have a minor effect on the results. As assessments are often performed with a set choice of Data and a set recycling rate, it is questionable how useful the results from this kind of LCA are for a policy maker. The high significance of the system boundary choices stresses the importance of scientific discussion on how to best address system analysis of recycling, for paper and other recyclable materials.

VTC-Fall - Multi-Technology Data Collection: Short and Long Range Communications
2017 IEEE 86th Vehicular Technology Conference (VTC-Fall), 2017Co-Authors: Ruben Oliveira, Lucas Guardalben, Miguel Luis, Susana SargentoAbstract:Low-Power Wide Area Networks (LPWANs) are a set of technologies that are growing in the field of the Internet of Things (IoT). Due to their long range capabilities and low energy consumption, LPWAN are the ideal technologies to send small Data occasionally. With their unique characteristics, LPWANs can be used in many applications and in different environments such as urban, rural and even indoor. The integration of one of the LPWAN technologies, Long Range (LoRa), in a multi-Technology Data gathering platform is the key objective of this work. This objective is addressed with the following proposed approaches: (1) an organization based in clusters of sensor nodes; (2) a Medium Access Control (MAC) protocol that provides reliable communications through LoRa Technology; and finally, (3) a connection manager that selects which wireless technologies should be used simultaneously to forward the sensing Data, according to its classification. The evaluation experiments aim to understand which type of parameters can influence the performance of the overall proposed solution, as well as the advantages of a multi-Technology approach in a Data gathering platform. The results in a real scenario show that the proposed approach is able to achieve simultaneous multi-Technology communication while delivering different types of Data with reliability and low latency.
